MECHANICAL MUSlCAL INSTRUMENT.

Specification of Letters Patent. 7

Patented Aug. 28, 1906.

Application filed July 28. 1904. Serial No- 218,538.

To all whom it may concern: Be it known that I, Lnwrs B. DoMAn, acitizen of the United States, and a resident of Elbridge, Onondaga county, New York,'have provided at one end with a spindle or pin provided at diametrically o posite points with projecting wings adapte to be received in suitable slots formed in the wall of a socketed coupling-head which is rotated by suitable means to wind the music-sheet on the spool connected therewith when desired.

To connect the spool and such coupling-head, it is necessary that the parts be arranged in such a manner that the fins or Wings on the spool-spindle are in alinement with the slots in the socket of the couplin head, and as said head is often so arranged that the slots therein are not clearly or readily seen by the operator considerable time is frequently reuired to adjust the spool into such position t at it may be engaged'by said coupling.

' One of the objects of this invention is to provide a construction by which the spindle of a music-spool may be inserted in the socket of the coupling on the rewinding-shaft without requiring the operator to first adjust its position relative to said socket with the care and precision necessary when using 7 the constructions heretofore in use.

A further object of the invention is to provide a spool for a mechanical musical instrument which can be employed in connection with the common or ordinary rewinding means as well as with those especially designed for it.

The invention is illustrated in the accompanying drawings, referring to which.-

Figure 1 is a slde view of a music-spool and its rewinding mechanism, constructed in accordance with the present invention, show ing the same in playing position. Fig. 2 is anend elevation of the spool. Fi 3 is an elevation of the end of the rewin g-shaft adjacent the spool. Fig. 4 is a view illustrating the manner of using the s ool with a rewinding mechanism of the or inary form,

Referring to the drawings, it will be seen that the spool comprises two heads 1 2,]connected by a central body 3 and provided with spindles 4 5. The means for supporting the spindle 4, as shown, is a spring-pressed bearing 6, into which said spindle extends, as is common, and the spindle 5 is shown as pro vided with the usual fins or wings 7, arranged at diametrically opposite points. The spindle 5 is adapted to extend mto the socket of a coupling-head 8, arranged at the inner end of a shaft 9, which by means of a suitable clutch -(conventionally illustrated at may be connected with ain a gear 11.

Tt will be seen that the bore or chamber the socket in the coupling-head=8-is of such diameter that the spindle 5 and wings 7 can move freely therein and that the slots commonly formed in the Walls of said couplinghead to-receive said wings or fins are dispensed with.

In order that the spool may be positively driven from the shaft 9, the head 2 thereof is provided with a projection (shown as a pin 12) which extends parallel to the spindle 5 at one side thereof and into the path of a radially-projecting lug or pin 13 on the couplinghead 8. It will thus be seen that the spool and shaft ,9 will rotate together, and when power isapplied to said shaft the spool will be positively rotated to wind thereon the music-sheet.

Owing to the proportions of the parts the spindle 5 ma be readily inserted in or removed from t e coupling 8, no care bein repower mechanism includquired to properly position the fins or Wings 7, as is necessary where the ordinary connection between the spool and its rewindingshaft is employed. However, the spool above described can be used with rewindin devices of the common form, if so desire This is illustrated in Fig. 4, in which is shown a rewinding-shaft 9, provided at its inner end with a socket-piece of common constructionthat is, having slots such as indicated formed therein to receive the fins on the spindle 5 of the music-spool. In such a construction the pin or projection 12 on the spool lies at one side of the coupling, and conor wings 7 M neotion between said coupling and the spool l rj ing journals provided with sockets for said is effectedby the Wings or fins 7 engaging l spindles, and a driving member for the roll 15 slots in the coupling instead of a radial proi carried by one of said journals and adapted jeictingilug 13 on the coupling engaging the i to cooperate with said pin on one of the rollprojection 12, as in the form first described. I

Having thus described the invention, What i is claimed, and desired to be secured by Letters Patent, is-

The combination with a music-roll having flanges and spindles at its ends and having a pin projecting from one of its flanges adapted to cooperate with a driving member, of a me chanical musical instrument having roll-carflanges, for the purpose set forth.

In testimony whereofl have sign'ed my i name to this specification in the presence of 2o l two subscribing witnesses:
